About apparatus
The speciality corrects the new equipment of teacher and AV installation personnel, Datacolor ColorFacts Professional furnished with the full-color user interface of built-in hardware and ocular, configurated, reduces and corrects required time greatly, guarantee updated accuracy grade, the correction which is suitable for various display screens at the same time, outstanding image quality that is abundant of letting the display screen manifest true nature, detail, promote the vision to enjoy in an all-round way. Through the optimization of Datacolor ColorFacts Professional, can give full play to the best display effect of the display unit.
Adopt the third generation Spyder chromascope (have ambient light test function, the precision is 0.0001)
Apparatus staging purpose
The basic goal of introducing this kit lies in being can be adjusted through the professional system, in order to show the optimum performance of all kinds of display equipment. Relatively luminance chromascopes adopted in the past, though could offer chroma and luminance data of products of all kinds of assessment and test, but lack the data analysis system of a system, so that can't let the ordinary net friend who lacks the professional knowledge understand the meaning among them. So, the digital family of celestial pole will use this new system and can bring the professional test that have the readability even more and analyze for the masses of net friends.
Assess and test the step preface to optimize
The day before yesterday to lasting products been digital family extremely reveal when characteristic evaluate, will use HIVI CAST to carry on the previous foundation and reuse TOPCON BM-7A luminance chromascope to test in order to receive basic reading optimally first, and can assist contrast degree, colour gamut equipotency out to measure the number value of the display characteristic through the basic software of the chromascope; But this kind of basic software is more to facing industrialized domain workers; As to ordinary net friend, the readability is lower.
In view of this, staging has adopted this set of ColorFacts systems at present, the foundation optimizes the step in we will keep original HIVI CAST in assessing and testing the step preface, but the brand-new article of assessment and test will omit contrast degree and black location test chart of HIVI CAST. The reason is very simple, with revealing the technical fast development, most models can already pay and recognize it correctly, certainly if necessary we will combine the detailed conditions to weigh.
HIVI CAST black location and grey scale test
Optimize tentatively through HIVI CAST, we will work optimally according to the actual conditions of the display equipment. Mention optimizing here, have to propose D65 color system standard, as a working standard in the world, D65 has already been applied numerous fields of dealing with etc. to television production, filming, picture extensively. Because this text is used mainly for introducing ColorFacts kit system, does not launch too much here, but as being thought extensively with the applied industrywide standard, for judging the precision that the display equipment reduces the signal source is absolutely authoritative by the world, so we go on, put emphasis on while being necessary in here. About D65 canonial detailed introduction article, the digital family of celestial pole will put out after several days too, please look forward to.

But while following D65 standard to optimize, it is not each display equipment that can adjust the work, and not that all display equipment that can be adjusted can be adjusted to the normal condition of D65, this relates to autogenous design level of the display equipment. Why need to optimize by oneself? Because according to present actual conditions, a great deal of display equipment manufacturers will not totally follow the standard of D65 to accomplish it in original mode. So ask users to remember some: " the good image quality is adjusted out " .
Prerequisite adjusted to go on according to the intersection of D65 and standard, display equipment must have the intersection of RGB and gain to noise temperature ratio and the intersection of RGB and self-defining to adjust the function deflection,etc.. And we it optimizes does wanted to be to use the colored to go on, adjust in order to make every effort, reach or close the standard of D65 to display equipment function; Certainly having self-defining tune-up function that much display equipment do not possess RGB, we will follow the detailed conditions, use HIVI CAST carry on foundation adjust, elect several piece representative to preserve the mode to go on and evaluate; If model possesses RGB self-definingly and adjusts the function, then we not merely can provide the result after optimizing, still can compare with its preserving the result under the mode, thus give readers a more overall understanding.
Reveal the test of contrast degree
Contrast degree reveals one of an important parameters of equipment performance as reflecting, the level of this ratio will influence the whole lay of graphics of the picture directly. In HIVI CAST foundation of having the page and referring to is optimized, among them some very important operation steps are to optimize contrast degree to the display equipment, most model at the market higher in luminance under the mode of preserving at present, can the intersection of image and dark location of picture behave also besides being dazzling, reasonable tune-up make the intersection of output and luminance reduce while being appropriate, offer, watch can the black of the picture become deeper and abundanter too while in comfort. Page several will provide the actual operation case after herein, it is ANSI contrast degree to be with one dose of icons of 16 palaces among them, half deceive half white icon for the intersection of ON/OFF and wide-open the intersection of full-turn-off and contrast degree.
Colorfacts kit offers two kinds of contrast degree test items
ANSI contrast degree
For let, test, try hard, watch the intersection of video and content of program at ordinary times by the intersection of simulation and user, canonial 16 palaces of dose reveal black-and-white picture at the same time after ColorFacts system has adopted ANSI, improve the contrast degree of the display screen by avoiding adopting some false trends technology in a poor light within the TV, because users are while watching the video program, can really contact all all black white chances are suitable and few.
